河南省国土经济密度时空分异特征及驱动力研究

Analysis of Temporal-Spatial Variation Characteristics and Driving Forces of Land Economic Density in Henan Province

研究区域国土经济密度,探究某时段内空间分异特征及驱动力,可以为提高土地利用效率和实现区域可持续发展提供重要参考。本文以河南省为研究区,测算1996-2016年河南省18个地(县)级市的土地经济密度时空变化情况,并利用Pearson相关分析对影响土地经济密度变化的驱动因素进行分析。研究结果表明,在时间上,1996-2016年全省土地经济密度整体呈增长趋势;在空间上,全省土地经济密度由中部向北部、西部、东部、南部逐渐递减,各区域间差异明显,区域发展不均衡;通过分析影响土地经济密度的各驱动因素可知,未来的经济发展应该充分发挥豫中和豫北地区核心带动优势,构建铁路枢纽轴带发展模式,以创新驱动加速产业结构升级,促进全省经济协调、均衡发展。

Studies on regional land economic density,exploring temporal spatial variation and driving forces can be critic for us to propose countermeasures to improve land use efficiency and be aware of the regional sustainable development.This paper takes Henan Province as the study area,attempting to estimate the temporal and spatial variation of land economic density from 1996 to 2016 in 18 （county）city of Henan province,and analyzing driving factors of land economic density by Pearson correlation.The results show that the overall land economic density in the province was increasing from 1996 to 2016 and gradually decreasing from the central to North,West,East,South.There are obvious difference among various regions,and regional development is not balanced.By analyzing the driving factors that affect the land economic density,we can draw a conclusion that the economic development in the future should give full play to the core driven advantage of central and north area of Henan,thus constructing the axial belt of railway center development model,driven by innovation to accelerate industrial structure upgrading,promoting the coordinated and balanced development of economic in Henan province.
